This tuning, named "C# Standard," presents an intriguing sonic landscape on the guitar. The original description suggests a search for a C# Standard tuning, and while this tuning bears that name, it offers a unique twist on the traditional C# Standard setup, creating an exceptionally deep and resonant sound profile.

The low C# (C2#) and F# (F2#) strings provide a powerful, deep foundation, immediately setting a heavy tone. However, this tuning significantly deviates on the middle strings. The 4th string is tuned a full octave lower than its typical position in a conventional C# Standard (B2), landing at an astonishingly low B1. Similarly, the 3rd string is also an octave lower than expected (E3), tuned to E2. This creates a surprisingly profound and almost baritone-like depth for these middle strings, fundamentally altering the instrument's harmonic and melodic possibilities. The higher strings, G#3 and C#4, then return to their expected pitches for a C# Standard setup, offering a familiar, albeit darker, top end.

Technically, the full tuning is C#2 F#2 B1 E2 G#3 C#4. The most notable features are the very deep B1 and E2. From the 6th (C#2) to 5th (F#2) string, the interval is a perfect fourth (5 semitones). Between the 5th (F#2) and 4th (B1) strings, there's an augmented fourth or diminished fifth (6 semitones), creating a unique tension. Between the 4th (B1) and 3rd (E2) strings, it's a perfect fourth (5 semitones). From the 3rd (E2) to 2nd (G#3) string, it's a major third (4 semitones), and from the 2nd (G#3) to 1st (C#4) string, it's a perfect fourth (5 semitones).

This specific tuning lends itself beautifully to very heavy, detuned riffing, sludgy metal, drone music, or experimental compositions due to its profound low-end capabilities. Open chords will be significantly re-voiced compared to standard tunings. For instance, a common power chord shape using the 6th, 5th, and 4th strings will produce C#2, F#2, B1, giving a thick C#5 with a very deep, resonant B note that adds immense weight. While traditional chord shapes will need significant adaptation, the unique intervals offer fresh sonic possibilities. Players accustomed to Drop C# or standard C# tuning will find familiar patterns needing significant re-evaluation, opening up new creative avenues for intricate low-end harmonies and unique voicings that can sound both powerful and haunting.

Here are the notes for each string in this "C# Standard" tuning, from thickest to thinnest:

• 6th String (Low E position): C#2
• 5th String (A position): F#2
• 4th String (D position): B1
• 3rd String (G position): E2
• 2nd String (B position): G#3
• 1st String (High E position): C#4

How to Tune:

To achieve this unique "C# Standard" tuning, follow these adjustments. The movements described below indicate how to reach the target note for each string. Always tune carefully and listen to your instrument.

• 6th String (C#2): Keep as is; no change (0 semitones).
• 5th String (F#2): Keep as is; no change (0 semitones).
• 4th String (B1): Keep as is; no change (0 semitones).
• 3rd String (E2): Keep as is; no change (0 semitones).
• 2nd String (G#3): Tune down 1 semitone.
• 1st String (C#4): Tune down 1 semitone.

Important Note on String Gauge: Generally, if a tuning requires moving a string by more than 4 semitones up or down, it is advisable to consider a different string gauge to ensure proper tension, intonation, and to prevent string breakage or damage to your instrument. For this tuning, the required changes are minimal (1 semitone down at most), so a standard gauge should be sufficient, but always listen to your instrument and consult a professional if unsure.
